1. The appellant, Douglas Mochache Ongaga, was convicted of the offence of defilement contrary to section 8(1) as read with section 8(3) of the Sexual Offences Act and sentenced to twenty (20) years' imprisonment.
2. Aggrieved by both the conviction and sentence, he lodged the present appeal challenging both conviction and sentence on the grounds that the learned trial magistrate erred in law and fact by finding that the offence had been proved beyond reasonable doubt, relying on insufficient and contradictory evidence, placing undue reliance on the medical evidence and the prosecution case despite alleged inconsistencies, and imposing a sentence of twenty (20) years' imprisonment without properly considering the circumstances of the case. He accordingly prays that the appeal be allowed, the conviction quashed and the sentence set aside.
3. The appeal was canvassed by way of written submissions. The appellant filed written submissions dated 13th May 2026 in support of the appeal. Despite being granted an opportunity to do so, the respondent did not file any submissions. The appeal therefore falls for determination on the basis of the record of appeal, the grounds set out in the petition of appeal and the appellant's written submissions.
4. This being a first appeal, this Court is guided by the principles in Okeno v Republic [1972] EA 32, where the former Court of Appeal for East Africa held that a first appellate court is obliged to subject the evidence to a fresh and exhaustive examination, weigh the conflicting evidence, draw its own conclusions, and make due allowance for the fact that the trial court had the advantage of seeing and hearing the witnesses.
5. The prosecution was required to prove all the essential ingredients of the offence of defilement beyond reasonable doubt. These are the age of the complainant, proof of penetration, and positive identification of the perpetrator. In Sumba v Republic [2024] KECA 521 (KLR),the Court of Appeal reaffirmed that these are the critical ingredients of the offence of defilement and that each must be established by credible evidence before a conviction can be sustained.
6. Having carefully considered the petition of appeal, the record of the trial court, the evidence adduced before the trial court and the appellant's written submissions, the issues that arise for determination are whether the prosecution proved the age of the complainant, whether penetration was established, whether the appellant was positively identified as the perpetrator, and whether the conviction and sentence imposed by the trial court ought to be disturbed.
7. In Nyokabi v Republic [2024] KECA 1199 (KLR), the Court of Appeal reiterated that the ingredients of the offence of defilement are that the complainant is a child, that there was penetration, and that the perpetrator was positively identified. The prosecution must therefore adduce credible evidence establishing the complainant's age beyond reasonable doubt.
8. The first issue for determination is whether the prosecution proved the age of the complainant beyond reasonable doubt. Age is an essential ingredient of the offence of defilement since it determines both the commission of the offence and the sentence prescribed under section 8 of the Sexual Offences Act.
9. In the present case, the prosecution proved the age of the complainant through both oral and documentary evidence. PW4, the complainant's mother, testified that the complainant was born on 14th May 2010. Her evidence was corroborated by PW7, the investigating officer, who produced the complainant's birth notification as Exhibit 4, confirming that the complainant's date of birth was 14th May 2010. The alleged offence having occurred on 09th and 10th October 2023, the complainant was 13 years old at the time. I am therefore satisfied, as was the trial court, that the prosecution proved the complainant's age beyond reasonable doubt.
10. The next issue is whether the prosecution proved the element of penetration. Section 2 of the Sexual Offences Act defines penetration as the partial or complete insertion of the genital organs of one person into the genital organs of another. While medical evidence is desirable in proving penetration, it is not indispensable where there is credible and cogent direct evidence establishing the fact of penetration. The Court must therefore evaluate the complainant's testimony together with the medical and other evidence on record to determine whether this essential ingredient of the offence was proved beyond reasonable doubt.
11. The complainant testified that the appellant removed her clothes, undressed himself and had sexual intercourse with her on two occasions. Her account was consistent that the appellant inserted his penis into her vagina, causing her pain. Her evidence was corroborated by the medical evidence of the clinical officer, who examined her shortly after the incident and observed that the hymen was broken, although there were no fresh injuries or bleeding. A P3 Form and treatment notes were produced in evidence. Upon re-evaluating the entire record, I am satisfied that the complainant's testimony, read together with the medical evidence, established the fact of penetration beyond reasonable doubt.
12. The final issue for determination is whether the prosecution proved beyond reasonable doubt that it was the appellant who defiled the complainant on the dates alleged.
13. The complainant testified that on 09th October 2023 the appellant instructed her to take the baby to his bedroom and later to sleep there with the baby, after which he returned, removed her clothes and defiled her. She further testified that on 10th October 2023 the appellant again instructed her to take the baby to his bedroom, later directed her to bring him water and thereafter pulled her onto the bed and defiled her.
14. PW2 confirmed that on the morning following 09th October 2023, the complainant informed her that the appellant had removed her clothes and done bad things to her in his bedroom. PW2 further testified that on the following night she witnessed the appellant instruct the complainant to sleep in his bedroom with the baby. PW2 also stated that the complainant later informed her that the appellant had done the same bad things to her. The evidence of PW2 therefore materially corroborated the complainant's account of the events leading to the offences and her prompt disclosure thereafter.
15. The medical evidence equally supported the complainant's account that penetration had occurred. PW6 observed bruises and blisters on the complainant's genitalia together with red blood cells in the high vaginal swab, findings which she concluded were consistent with penetration. Although PW6 testified that the complainant disclosed having engaged in sexual intercourse with her boyfriend on 15th October 2023 and admitted that she did not record that history in either the treatment notes or the PRC Form, that omission did not displace the direct and credible evidence of the complainant identifying the appellant as the person who defiled her. The medical evidence was corroborative of penetration, while the identity of the perpetrator was established by the complainant's testimony as materially corroborated by PW2.
16. The appellant denied the charge. In Stephen Nguli Mulili v Republic [2014] KECA 408 (KLR), the Court of Appeal reaffirmed that the prosecution must discharge that burden and that nothing short of proof beyond reasonable doubt will suffice.
17. Upon my own independent evaluation of the evidence, I am satisfied that the complainant was a truthful witness whose evidence was materially corroborated by PW2 and supported by the medical evidence confirming penetration. The omission by PW6 to record the complainant's subsequent sexual encounter did not create a reasonable doubt in light of the cogent evidence identifying the appellant as the perpetrator.
18. I therefore find that the prosecution proved its case beyond reasonable doubt and that the conviction was safe. The appeal against conviction is accordingly dismissed. The sentence of twenty (20) years' imprisonment is hereby upheld but shall run from 15th October 2023, being the date on which the Appellant was arrested.
